Security-oriented fuzzer with powerful analysis options. Supports
evolutionary, feedback-driven fuzzing based on code coverage
(software and hardware).

libb64 is a library of ANSI C routines for fast encoding/decoding data into and
from a base64-encoded format. C++ wrappers are included, as well as the source
code for standalone encoding and decoding executables.

msitools is a set of programs to inspect and build Windows Installer
(.MSI) files. It is based on libmsi, a portable library to read and
write .MSI files.

msitools plans to be a solution for packaging and deployment of
cross-compiled Windows applications.

The tool does the following:

1. Extracts input packages
2. Searches for *.debuginfo, *.so and header files
3. Creates ABI dumps of all found shared objects
4. Filters out private part of the ABI using info from header files
5. Matches shared objects in old and new packages
6. Compares ABI dumps of corresponding objects
7. Creates backward binary/source compatibility reports
The pkg-abidiff tool is based on the ABI Compliance Checker tool. It is executed on every shared object found in the RPM. You can find reports of the ABI Compliance Checker by following the links in the "Shared Objects" section of the output report: https://abi-laboratory.pro/examples/compat_report/x86_64/libssh4/0.5.3-2.1.1/0.6.3-8.1/

The ABI Compliance Checker tool is designed to compare particular shared objects (or debug info ABI dumps). The pkg-abidiff is designed to compare sets of shared objects in RPM packages. Also it searches for all necessary data in RPMs and provides all necessary options to ABI Compliance Checker.

A tool for visualizing changes in Linux software packages (RPM, DEB, TAR.GZ, etc).
The tool is intended for Linux maintainers who are interested in ensuring
compatibility of old and new versions of packages.

Radamsa is a test case generator for robustness testing, aka a fuzzer. It
can be used to test how well a program can stand malformed and potentially
malicious inputs. It operates based on given sample inputs and thus
requires minimal effort to set up. The main selling points of radamsa are
that it is easy to use, contains several old and new fuzzing algorithms, is
easy to script from command line and has already been used to find a slew
of bugs in programs that actually matter.

Rtags is Clang based source file indexer supporting C/C++/Objective-C(++) code.

Sysdig is open source, system-level exploration: capture system state and
activity from a running Linux instance, then save, filter and analyze.
Think of it as strace + tcpdump + lsof + awesome sauce. With a little Lua
cherry on top.

The basic idea is fairly simple. As 'fuzz testing' suggests, we call syscalls
at random, with random arguments. Not an original idea, and one that has been
done many times before on Linux, and on other operating systems. Where
Trinity differs is that the arguments it passes are not purely random.

Txt2man converts flat ASCII text to man page format. It is a shell
script using gnu awk, that should run on any Unix like system.

It is intended for developers of software libraries and maintainers of Linux
distributions who are interested in ensuring backward binary compatibility.

The tool is developed by Andrey Ponomarenko

Tools for building software

ccache is a compiler cache. It speeds up recompilation by caching the
result of previous compilations and detecting when the same compilation is
being done again. Supported languages are C, C++, Objective-C and
Objective-C++.

GYP is a tool to generates native Visual Studio, Xcode and SCons and/or make
build files from a platform-independent input format. Its syntax is a universal
cross-platform build representation that still allows sufficient per-platform
flexibility to accommodate irreconcilable differences

to quote wikipedia:
Software Configuration Management (SCM) is part of configuration management (CM). Roger Pressman (in his book) Software Engineering: A Practitioner's Approach, says that software configuration management (SCM) is a "set of activities designed to control change by identifying the work products that are likely to change, establishing relationships among them, defining mechanisms for managing different versions of these work products, controlling the changes imposed, and auditing and reporting on the changes made." In other words, SCM is a methodology to control and manage a software development project.

SCM concerns itself with answering the question: somebody did something, how can one reproduce it? Often the problem involves not reproducing "it" identically, but with controlled, incremental changes. Answering the question will thus become a matter of comparing different results and of analysing their differences. Traditional CM typically focused on controlled creation of relatively simple products. Nowadays, implementers of SCM face the challenge of dealing with relatively minor increments under their own control, in the context of the complex system being developed.

This project contains normal text editors and special hexadecimal editors. Both for X11 and the console.

A fullscreen, distraction-free writing program. You can customize your
environment by changing the font, colors, and background image to add
ambiance as you type. FocusWriter features an on-the-fly updating word
count, optional auto-save, optional daily goals, and an interface that
hides away to allow you to focus more clearly; additionally, when you open
the program your current work-in-progress will automatically load and
position you at the end of your document, so that you can immediately jump
back in.

GNU Moe is a powerful, 8-bit clean text editor for ISO-8859 and ASCII character encodings. It has a modeless, user-friendly interface, online help, multiple windows, unlimited undo/redo capability, unlimited line length, global search/replace (on all buffers at once), block operations, automatic indentation, word wrapping, filename completion, a directory browser, duplicate removal from prompt histories, and delimiter matching.

GNU nano is a small and friendly text editor. It aims to emulate
the Pico text editor while also offering a few enhancements.

GTK UI for Neovim written in Rust using gtk-rs bindings. With ligatures support.
